100% - 10% = 90%
HazelEmily =
90100 =
910 Combined salaries at first
= 9 u + 10 u
= 19 u
Decrease in the combined salaries
= 40% x 19 u
=
40100 x 19 u
= 7.6 u
Combined salaries in the end
= 19 u + 7.6 u
= 11.4 u
11.4 u = 5586
1 u = 5586 ÷ 11.4 = 490
Emily's salary before the decrease
= 10 u
= 10 x 490
= $4900
Answer: $4900
